Summary
The Polygon Collosus is praised for its modern enduro geometry, offering a planted and predictable ride that excels in high-speed descents and corners. It provides impressive value for money with solid build kits and efficient suspension performance, though its heavy weight can hinder playfulness and climbing agility. While the bike requires careful setup to optimize handling, it delivers a capable and comfortable experience for aggressive riding.
Modern enduro geometry
Good value for money
Efficient suspension performance
Planted and predictable handling
Solid build kit
Heavy weight
Requires careful setup
Limited playfulness
Draggy tires
High maintenance due to multiple pivots
It dived in and out of a snaking section of steep, supported corners in a solid, predictable manner and the dimensions felt good.
BikerumorIndeed it’s a bloody good enduro bike for the money, and one that is perfectly at home riding the roughest and rowdiest gravity-fuelled descents.
Flow Mountain BikePolygon once again delivered an impressive bike for the money.

The Polygon Collosus N7 is the cheapest way to purchase in new enduro mountain bike in 2023. But does that mean it's worth buying? Spoiler Alert: It's for the park rats 🐀
Extremely affordable
Relatively solid spec given the price
Great performing suspension (one you set it up correctly)
Well rounded geometry
Weight (41 lbs / 18.6 kg tested)
Weak brakes
Minimal dropper post insertion
May 2026
Polygon's premier trail rig has great handling and comes in at $3k+ cheaper than rival offerings.
Impressive value: 7700 CAD for full Shimano XTR Di2, RockShox dampers, carbon frame
Adjustable geometry: flip chip for 29/27.5 rear wheel, headset cup slackens HTA, BB height adjustment
Light weight: estimated 31 lbs
Lively climbing with high traction and steep seat angle
Active, plush suspension with decent pedaling platform
Shimano XTR Di2 shifts smoothly and quickly
XTR brakes have predictable ramp-up and good lever feel
Double Dissector tires lack front grip, need aggressive front tire
170mm dropper insufficient for steep terrain, desire 200mm+
Brake rotors small (180mm front), prefer larger
Climb switch reduces traction and feels awkward
Latch mechanism releases vaguely

The latest from Polygon Bikes is the Collosus T, an aggressive new trail bike model that’s surprisingly affordable.
